14 hatch 13 ov 13 gas 16 pool has been one of my fav starts for 2s and 1v1 lately. I watched catz and hydra both do it and it leaves u open to sling and bane in zvz or go quick roach depending on whats going on. you can also do a ez 3rd hatch around 22 like i do vs t. I am a top plat almost to diamond so all you gold and lower players maybe this can help you. I just thought I would share it for all you other zerg players. you can message me here anytime if you want some replays
